等效折射率 meaning in English
refractive index difference
Examples
- The effective index method is applied to simplify an awg structure from 3d to 2d . two simulation methods are presented in detail based on the gaussian beam propagation formula and the finite difference beam propagation method
文中采用等效折射率方法把三维结构简化为二维结构，然后分别基于高斯光束的传播和有限差分光束传播方法( fd - bpm ) ，给出了两种对整个awg进行全局模拟的具体方法。
